A well formed, hexagonal, brown corundum crystal from this old corundum mine. Historic!
From mindat:
This deposit was the province's first producer of corundum and was discovered in 1876 but was not mined until 1900. It is a syenite pegmatite in an albite-nepheline gneiss. The largest crystal of corundum is reported to be 8 inches by 6.25 inches. Zeolites have also been reported to occur there.
The Craigmont mine was operated from 1900 to 1907 by the Canada Corundum Company, Limited. From 1908 to 1913 the mine was leased to the Manufacturers Corundum Company. On February 3, 1913, the mill at Craigmont was destroyed by fire. In 1919, Corundum, Limited, leased the properties of the Manufacturers Corundum Company and built a new 100-ton mill at Craigmont to treat tailings, of which it was estimated there were 300,000 tons. Grain corundum was produced from December 1919, until the mill closed down in June 1921. (ARV53)
